Abstract

um sistema para atenuar o ruído coerente a partir de dados sísmicos compreende um ou mais sensores configurados para detectar ondas geradas por uma fonte sísmica, e um módulo de atenuação de ruído coerente comunicável acoplado ao um ou mais sensores e que compreende um processador e memória. o módulo de atenuação do ruído coerente é operável para receber uma pluralidade de traços de dados sísmicos a partir de um ou mais sensores e aplicar uma primeira transformação à pluralidade de traços, identificar uma ou mais formas de onda de valor atípico nos traços transformados, atenuar as formas de onda de valor atípico identificadas, e aplicar uma segunda transformação à pluralidade de traços que é o inverso da primeira transformação.
